Abstract

While skeletal muscle is often assumed to be structurally transversely isotropic, its mechanical anisotropy is not well characterized in vivo. Such in vivo characterization can be achieved using VisR ultrasound, a technique that provides information about the viscoelastic mechanical response of tissue. Specifically, VisR-derived Relative Elasticity (RE) provides directionally dependent information about the shear modulus of materials. We hypothesize VisR RE can be used in healthy older adults and in stroke patients to 1) assess the degree of anisotropy (DoA) of the biceps brachii (BB) and 2) characterize the effect of passive loading on the BB.
